                               Introduction In our previous article, we introduced you to the concept of branches in git. We explained what are branches and demonstrated how we could create a branch, switch to a different branch and delete a branch. In this article we will demonstrate how we use branches to prototype our work while keeping a functioning copy of our work available in the master branch. Demonstration Let’s start by creating a new branch and then move in to that branch. [sahil@linuxnix perl_scripts_for_training]$ git checkout -b my_branch Switched to a new branch 'my_branch' [sahil@linuxnix perl_scripts_for_training]$ Now we will make a commit on this branch by modifying the perl script hello.pl. [sahil@linuxnix perl_scripts_for_training]$ cat hello.pl #!/usr/bin/perl -w ###################################### #Author: Sahil Suri #Date: 24/03/2018 #Purpose: Hello World in Perl #version: v1.0 ###################################### print "Hello World\n"; print "Hello World again.\nMy name is Sahil.\n" [sahil@linuxnix perl_scripts_for_training]$ I’ve updated the script such that it has the below content now: [sahil@linuxnix perl_scripts_for_training]$ cat hello.pl #!/usr/bin/perl -w ###################################### #Author: Sahil Suri #Date: 24/03/2018 #Purpose: Hello World in Perl #version: v1.0 ###################################### print "Hello World\n"; print "Hello World again.\n" [sahil@linuxnix perl_scripts_for_training]$ Now we will add and commit these changes. [sahil@linuxnix perl_scripts_for_training]$ git add . [sahil@linuxnix perl_scripts_for_training]$ git commit -m 'updated hello.pl' [my_branch 2d3806c] updated hello.pl 1 file changed, 1 insertion(+), 1 deletion(-) [sahil@linuxnix perl_scripts_for_training]$...

                               Introduction Thus far we’ve explored different features of the GIT version control system like viewing a log of the git commit history, viewing differences between staged and committed versions of files. We also explained the concept of HEAD and explored how we could use the git checkout command to revert to previous versions of files and most recently we demonstrated how we could integrate and store our local repositories remotely on GitHub, a service for storing all the git related data on our local systems. In this article, we will be explaining one of the most important features of the git version control system i.e. branching. What are branches? Thus far we’ve been making all our commits on the master branch. In this article we will demonstrate how we can create more branches. When we start working with more complicated workflows we need to be ensure that we have a stable state of our data to return to. Therefore, while using git we take care that the master branch always contains code that can execute without failure. But we still want to make commits while we are testing our code. In this scenario we use branches. In the above image we have a master branch and we have a branch named my_branch which also...
